兰考泡桐根材和枝桠材解剖特性和基本密度的研究

A STUDY ON THE ANATOMICAL STRUCTURES AND WOOD PROPERTIES OF ROOTS AND BRANCHS OF ELONGATE PAULOWNIA

测定研究了不同直径兰考泡桐的根材和枝桠村的各种解剖因子及其基本密度。结果表明：兰考泡桐根材和枝桠材构造区别明显，不同直径的根材和枝桠树木材解剖特性和基本密度均有变异，仅少数指标差异显著；根材和枝桠材相比，基本密度和木纤维含量为枝材＞根材，其余因子均为根村＞枝材。进一步分析论证表明，根材和枝桠材是刨花板的好原料；而枝材适宜于生产纤维板，但根材不合适。

The determination of the anatomicial features and their basic density of the different diameter branchs and roots of Elongate paulownia showed.That the wood microstructurs of roots and branchs are remarkable different and can be identified easily. The anatomical features and basic density of the different diameter roots and branchs vavied greatly or less,but only a few parameters have significant differences among the different diameters. To compare the wood properties of the branchs with those of the roots,the basic density and proportion of wood fiber are more than those of the roots,on the contrary,the other wood anatomical features of the branchs are less than those of the roots. The roots and branchs are most cuitable for producing particle board;And branchs can be used to manufacture fibre board,but the roots can be not.
